Pittsburgh Pirates vs. San Francisco Giants Prediction

I’m on the Giants here. San Francisco has struggled mightily but in current form it feels like nothing could cure what ails you more like a game against Mlodzinski, who has allowed 5 runs in each of his last three starts. The Giants should be able to do enough damage here and while the Pirates are winning games over the last week, the offense hasn’t been all that convincing in that stretch so I think this could be a prime spot for San Francisco to steal one here. Give me the Giants.
